v. The act of maserbating and someone interrupts the act, just at the point of climax but before the actual ejaculation, so you have no option but to just put your junk back in you pants and cum all over the the inside of your shorts.

Me: My mom walked in just as I was ejaculating. I had NO time to cum on anything so I just shoved everything back in my pants and came all over myself. what a disaster.
